I guess what I am trying to figure out is how much is pulled from the httpd.conf for optimizations if any, how much is over-ruled by the LiteSpeed web interface if any and more detailed information on how they interact.

I set the MaxClients and ListenBacklog in httpd.conf both to 1 and then got the following results with LiteSpeed vs Apache:

----------------------------

The first results are with LiteSpeed and the httpd.conf of apache set to MaxClients 1 ListenBacklog 1

The second results are with Apache and the httpd.conf of apache set to MaxClients 1 ListenBacklog 1

I then set the Max Connections to 1 in the litespeed configuration and repeated the litespeed test which resulted in approximately the same results as the first test.

I then set all the keepalive, caching, and buffering options to 0 that I could find and still it completed all 1000 requests with no failures.

This is not really clear either way as to what is going on, I theorize that the LiteSpeed equivalent of the ListenBacklog setting of Apache is allowing the connections to queue up and be completed, which if that theory is correct would mean that LiteSpeed is not using the httpd.conf for that optimization.

So what I am really trying to find out is how LiteSpeed's configuration and the httpd.conf interact.

same as MaxClients and ListenBacklog etc, although litespeed can read and understand(or ignore) these apache directives, litespeed won't follow and not necessary to follow, since their architecture is quite different, the implement detail can be different.

Thank you this helps quite a bit in understanding what is going on. You guys have a very nice product that looks to work very well, I have worked with quite a few of your enterprise level servers so far and the speed difference over Apache is noticable.

But if there is no documentation for it I need to know if there is a way I can see the current in-use variables for LiteSpeed, such as the following:

you can look at the real-time stats in admin console for traffic-related stats. the out of box configurations are good for most setups. if you have a specific performance issue, you can post on forum for free support or purchase a support ticket for fast turnaround.
